REMOVAL
1
on safety stands Drain gear od
2 Remove exhaust tube
3
panion flange
4 Remove drive shafts
5 With differential carrier jacked up,
remove diff mounting insulator nuts
6 Loosen off four fitting bolts that
hold differential carrier onto suspen-
son member
7 Pull off differential carrier back-
ward together with jack
Jack up rear of car and support
Disconnect propeller shaft at com-
SPD511
After carner assembly IS removed,
support suspension member
on a stand
to prevent its insulators being twisted
or damaged
Note Do not place the center of
suspension member on the stand
before removal operation Other-
wse, it wll be &fficult to extract
the
gear carrier assembly
PRE- DISASSEMBLY
INSPECTION
Differential carrier should be in-
spected before parts except rear cover
are removed from it
These inspections are helpful in
finding the cause of the problem and
in determining necessary corrections
1 Using three 45 mm (I 77 in)
spacers, mount carrier
on Diff Attach-
ment KV38100800
LKV38100800

2 Remove rear cover
3 Visually inspect parts for wear or
damage
4 Rotate gears checking for any
roughness whch would indicate dam-
aged bearings or chipped gears Check
gear teeth for scorlng or signs
of
abnormal wear Measure preload of
drive pinion

5 Set up a dial indicator and check
the backlash at several points around
